Apparatus, system, and method of communicating a physical layer (phy) protocol data unit (ppdu)

Abstract

For example, a wireless communication Station (STA) may be configured to generate a preamble of a Physical Layer (PHY) Protocol Data Unit (PPDU) according to a PPDU frame format. For example the STA may be configured to generate a data payload of the PPDU according to the PPDU frame format. For example, the data payload may include a plurality of data payload portions. For example, the PPDU may include a predefined Training Field (TF) between a first data payload portion and a second data payload portion of the plurality of data payload portions. For example, the STA may be configured to transmit the PPDU.
